do eeeet. My guess is it's simply the starting point of some over boost logic, and may require either a few more psi over that limit, or a time qualifier. It'd be great to see it set like 2psi lower than what you normally use.

I didn't have any problems with the meth, and remember the car ran ok the night before on the older map, so I don't think there was a vacuum leak anywhere, or the car would have run like shit the night after install....

I don't know if we'll every really know what caused the blow, especially with the limited data I have...

It honestly sounds mechanical to me. You were obviously over boosting, and the ecu appeared to be doing what he could to stop it (WGDC was 0's in that log). I think either a boost line popped off, or something screwed up with he actuator. Not sure.

I was putting off reading this thread bc I thought it was in response to the would you suck dick for $1B thread. Sorry to hear man, good luck...

Well, after Xmas I'll be able to pull the PG K04 off the car and take a look at it... all the hoses (all 2 of them) look fine going to the EBCS though...

If anyone wants to buy the PG K04 & PTP WGA, lemme know ;)

thanks!

The car is load tuned from the factory, so it has to allow for a lot of boost variation. Makes sense that boost limiting tables would be pretty soft.

Compare the two dynamics tables - load hits hard and early, boost is soft early then harder at extremes. I set a BOLO in my brain for "boost shit I never thought of" because I know there's things I haven't had to deal with in load tuning that will now show up with boost tuning. Today I put a modified load dynamics table in my boost dynamics table (the over side) to see what happens.

you should run the ebcs in 3 port mode. I don't know much...don't know anything, really...but I can help you start off with your WGDC table once you get up and running again...

But I don't know how many hands you want in your jar...you know? =)

I am starting to think my Grimm EBC is not working right. I have it setup in 3 port and my WGDC is still about the same as it was on the OEM BC. It is my understanding it should be about 50% less DC setup in interrupt mode...IDK

Fobio is yours that much less than OEM?

Are your vac lines properly connected for the EBC?

I believe so.....it is hooked up just like the instructions on their site indicate... but it does seem to be acting like it is running in 2 port.

easy enough to switch things around and see if I can VTA my block. haha I would of course knock my WGDC tables down first.


maybe I'll try that later today or tomorrow...

I did the EBCS's instructions and started off 30% lowered WGDC (by applying M to the table)...it was way too high...spiking 24psi...I never beat it like that, cuz it doesn't feel right.

this wouldn't be a problem if your upgrade was just the EBCS, but with the PTP WGA installed, 50% lowered WGDC was still too much. so I said eff it...I put 0's on the whole WGDC table, ran spring pressure, and were holding 18PSI...so I knew my preload was higher than I wanted by 2PSI, as I wanted preload to be 16PSI...oh well...

tuning from spring pressure, you first didn't have to worry about spikes, and I was also able to try a few things out without worried about blowing.

once my load curve/spikes were understood and contained on straight spring pressure, I then bgan to up WGDC to hit my boost targets and increase my load curve a bit at a time.

here's my current WGDC table:

oh..I forgot about your big WGA spring so that will skew the numbers for sho.

I may just have my WGA preload down to like 11-12PSI and just need to add a bit more preload so DC isn't so high.

thanks

Edit: just looked back at my WGA test logs and it is cracking at ~12PSI so I could go 1 more PSI maybe but IIRC 12PSI is about what the OEM K04 WG cracked at back when I tested it so IDK.

Dano, when I installed my Perrin EBCS in 3-port on the stock turbo I didn't change the WGDC at all and it worked perfectly. When I switched to the BNR, I had to set the table to 25% from 2250 up to begin.

so you lowered the entire table by 25% or set it to 25% of the original values?

You have a PM...

I set the table value to 25 across the board after 2250...

O I C...gotcha!
